Yankee GM Brian Cashman donned a flight suit and strapped a parachute to his back Monday morning and jumped out of a plane with the Golden Knights of the U.S. Army. The jump, from a plane based out of Homestead Air Force Base, is the latest in several stunts Cashman has performed to raise awareness for various causes, this one in support of the Wounded Warrior Project.

Cashman loved the initial jump so much that he went back to do it a second time, calling it "an incredible experience." But Round 2 wasn't as successful - Cashman injured himself upon landing, saying that he "heard a pop," when he came down.

Cashman suffered a broken right fibula and a dislocated right ankle following the second jump.

He is scheduled to have surgery later today at Broward Health Medical Center.

"I'm in great spirits, and it was an awesome experience," Cashman said in a statement. "The Golden Knights are first class. While I certainly didn't intend to raise awareness in exactly this fashion, I'm extremely happy that the Wounded Warrior Project is getting the well-deserved additional attention."

Yikes.

"It's a really sad thing to hear," said Yankees bench coach Tony Pena. "I just found out about it on the field. But Brian is a strong person. He'll bounce back. Thank God it wasn't worse."

Cashman should be able to perform his Yankees duties despite the injury, distinguishing him from several of the team's best-known players. Shortstop Derek Jeter is still recovering from his own fractured ankle, suffered in the 2012 ALDS. Closer Mariano Rivera missed most of last season after injuring his knee in May. And third baseman Alex Rodriguez will start the season on the disabled list while recovering from hip surgery.

The skydive was Cashman's first, but the Yanks' GM is no stranger to performing stunts for charity. For the last three years, Cashman has rappelled down a 22-story building in Stamford, Conn. as part of the city's Heights and Light Festival.
